LIGHTING AND HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 482,874, datedSeptember 20, 1892.

Application filed March 15, 1892. Serial No. 424,959. (No model.)

T0 aZZ whom it 11mg concern.-

Be it known that I, JAMES D. LUTHER, a resident of Brooklyn, Kingscounty, and State of New York, have invented an Improved Lighting andHeating Apparatus, of which the following is a specification, referencebeing had to the accompanying drawings, forming part hereof, wherein-Figure 1 represents a vertical central section of my improved lightingand heating apparatus. Fig. 2 is a bottom view of the drum used thereon.Fig. 3 is a top view of the apparatus without the drum.

This invention has for its object to supply ordinary gas-brackets withmeans for lighting and heating the room and for boiling water and thelike.

The invention consists of the new combination of parts hereinafter morefully specified.

In the drawings the letter A represents the end of the gas-pipe.

B is a hollow ring connecting with the gaspipe and carrying series ofgas-nipples O of ordinary or suitable construction. These gasnipples mayproject directly from the ring, as shown, or from arms thereon. In thedrawings I have shown four such gas-nipples on the ring; but a greateror less number may be employed.

From the ring B, or, if desired, from the pipe A, extend a series ofbrackets a to a height greater than that of the gas-nipples, as shown.

hese brackets a are adapted to support a drum D, which is open at thelower end and which, by preference, is closed, as at b, at the upperend. Between the upper and lower ends this drum has a diaphragm d, ofwiregauze or the like, and above this diaphragm the drum has a series ofair-holes e in the upper heating-chamber, formed between the top I) anddiaphragm d.

When my improved apparatus is desired for illuminating purposes,it isonlynecessary to light the gas at the ends of the gas-nipples 0, whenthe ordinary illuminating-flame will be produced, yet at the same timethe drum may be left in place on the brackets and the heat resultingfrom the illuminating-flames will in that case be to some extentcollected and given out by said drum. When, however, the apparatus is tobe used for cooking or particular heating purposes, I do not light thegas at the nipples C, but allow it to fiow into the drum mixed with airthat enters the lower end of said drum, and I then light the mixtn reabove the diaphragm d, thereby producing a strong heating-flame and theconsequent results of rapid boiling or the like of anything placed uponthe drum.

The apparatus is particularly useful to persons who occupy smallquarters and who desire from time to time to employ their gasbracketsfor the several purposes hereinbefore stated.

What I claim is- A lighting and heating apparatus consisting of thegas-pipe A, gas-ring B, having gasnipple O and bracket a, all arrangedbelow the drum D, open at its lower end and provided with the perforateddiaphragm d, said drum being imperforated below and perforated abovesaid diaphragm, substantially as and for the purpose specified.
